EMERGENCY ANGLE-COUPLING FOR BROKEN TRAIN-LINES.

Specification of Letters Patent.

Application filed April 15. 1918. Serial No. 228514.

To all whom it may concern:

Be it known that I, JOSEPH C. VENABLE, a citizen of the United States, residing at East St. Louis, in the county of St. Clair and State of Illinois, have invented a new and useful Emergency Angle Coupling for Broken Train-Lines, of which the following is a specification.

My invention relates to an emergency angle-coupling to take the place of an anglecock which has been broken off the train line or removed for any cause.

The object of my invention is to provide a simple device which may be easily and quickly afiixed to the air-pipe of a trainline, by the train crew, to take the place of an angle-cock which has been broken 01f the train line thereby obviating the necessity of removing the car from the train which has the broken train-line or switching the car to the front of the train next to the engine, or to the rear thereof next to the caboose.

With the above and other objects in view, the invention consists in certain novel features of construction, arrangement and com-' bination of parts as will be more fully de scribed hereinafter and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings forming a part of this specification wherein like characters of reference denote similar parts throughout the several views:

Figure 1, is a diagram of a train-line section under a car showing the usual anglecock at one end and my invention or emergency angle-coupling affixed to the other end thereof in lieu of anangle-cock.

Fig. 2, is a sectional view of my anglecoupling afiixed to a train-line pipe at one end thereof where the usual angle-cock has been broken off.

Fig. 3, is a sectional view taken on line AA of Fig. 1, but on a larger scale.

Fig. 4, is a detail in perspective of one of the pipe clamping-segments.

Referring to the accompanying drawings the reference character 1 designates the airpipe of a train-line which is located and carried under a car and connected between the cars by means of the usual air-hose 2 and the usual anglecock connection 3.

In carrying out the aim of my present invention I employ a female coupling member 4 which is interiorly threaded as at 5. Memher 4 is provided with an end wall 6 termb nating in a suitable neck 7 provided with an angular passage 8. The'outer end of the neck is interiorly threaded, as at 9, to receive the usual nipple 10 of an air-hose 11. The neck 7 is also preferably provided with a suitable wrench gripping shoulder 12.

A male member 13 is employed having the eXteriorly threaded surface 14 adapted for screw-threaded engagement with the female member 4, as clearly shown in Fig. 2 of the drawings. The male-member 13 is also provided with a suitable wrench gripping shoulder 15, as shown in Figs. 1 and 2 of the drawing so as to be .able to hold the same stationary while tightening member 4 thereon.

The male member 13 is provided with the air-pipe receiving opening or passage 16 through which is adapted to pass the broken end of a train line air-pipe designed 1.

The male member 13 is further provided with a tapered or cone receiving chamber 17 having the shoulder 18 adjacent the wrenchgripping end 15 thereof.

pair of suitable preferably semi-circular pipe clamping segments19 having a tapered periphery 20 to correspond to the tapered wall of the receiving chamber 17 is adapted to be carried inthe receiving chamber 17 between the shoulder 18 and the endwall 6 of the female member 4, as clearly shown in Fig; 2.

Each cone segment 19 is provided with a semi-circular passage 21, in cross-section, adapted to form a tubular passage when they are assembled, as shown in Fig. .3, to receive the train-line air-pipe v1.

A suitable packing ring 22 is interposed between the end wall 18 of the member 13 and the end faces 23' of the pipe clamping segments 19. A similar packing ring 24 is also interposed between the end wall 6 of the female member 4 and the end faces 25 of the pipe clamping segments 19. e

It will behere observed that when the several parts hereindescribed are assembled upon the broken end of a train line air pipe, as illustrated, that by tightening the member 4 upon'the member 13 that the pipe clamping segments 19. are forced or wedged to tightly grip the broken train line pipe 1 and also force or wedge its end faces 23 and 25 tightly against the packing rings 22 and 24, respectively to provide an air tight connection around and adjacent the pipe 1 at Patented May 20, 1919..

each end of the pipe clamping segments 19, as clearly shown in Fig. 2.

It will readily be understood from the foregoing specification that should the usual angle-cock 3 be broken off the train-line pipe 1 due to any cause or removal for repair that my angle-coupling can be readily and quickly applied in lieu thereof, thereby providing an emergency coupling which will effectively carry out all the functions of the usual anglecock exceptingthe function of the usual cutoif which is not necessary for an emergency coupling owing to the fact that the emergency coupling may be removed at the end of a run and a new anglecock fixed to the train line pipe 1, as is manifest.

Broken train lines are a source of nuisance to train men and the cause of unnecessary delay on the road and the cause is usually due to the angle-cock being broken off of the pipe 1 which is caused usually by the weakening of the pipe at'the threaded connection with the angle-cock.

lWIy angle-coupling may be carried by the train crew in the engine or in the caboose and may be applied quickly to a train line pipe when the occasion arises for its use.

The many advantages of the herein described invention due to the construction shown and method of application and adjustment to a. broken train line pipe will be readily apparent to those skilled in the art to which the invention appertains.

lVhile I have described the principle of application to a train line pipe and adjustment of the invention thereon, together with the structure of device I now consider to be the best embodiment thereof, I desire to have it clearly understood that the device shown is merely illustrative and that I reserve the right to make any such changes or modifications as may fairly fall within the principle of the invention and within the scope of the appended claims when fairly construed.
